A huge work under the results of FA 2013-2015 Fairy section is finished!
I believe, I may say from all of us a big Thank You! to the judges – Juraj Lörinc, Petko Petkov, Kjell Widlert – and the director of the section, Franz Pachl!

Don’t miss Quartz TT11:
Since 1996, Glasgow Chess was very poorly represented and our belief is that this genre has a lot of potential. So, we are launching a thematic tournament, Quartz TT11, for problems with Glasgow Chess rules.
The tourney has two sections: a) fairy problems; b) retro problems.
In both sections, combinations with other genres, fairy units, are allowed, but Vielväterstellung problems are not allowed.
Send problems in an unlimited number to our Director, Dinu-Ioan Nicula, e-mail: nicudin004@yahoo.com, up to July 1, 2018

I would like to introduce “Jacobi”, a new program that can solve fairy proof games. The home page is at http://wismuth.com/jacobi/. The program is a web app that runs in your browser and requires no installation.

It can solve proof games that Popeye struggles with, which by itself is a good enough reason to add Jacobi to your toolbox. There are also new possibilities like allowing undefined pieces in the diagram of a proof game.

That said, it is still far from being a “Natch/Euclide for fairy chess”. Jacobi’s introductory problem is in 9.5 moves, while Natch’s is in 22.5 and Euclide’s in 26.0. But this is the first version and performance might improve over time.

How to try Jacobi for people in a hurry:– copy any example problem from the home page to your clipboard– click on “Launch the latest version”– paste the problem into the box below “Text representation”– click on “Set problem from text”– click on “Start”.

Dear Friends, being one of the organizers of the 13th European Chess Solving Championship in Riga from Friday, May 12th to Sunday May 14th, I’m very much busy till the end of the event. I have to apologize for the delay in publications on JF. Please, send your original problems starting May 16th and I’ll be glad to publish them!

Dear all, We proudly inform you that the official web site for the 60th WCCC /41st WCSC held in Dresden (August 05-12, 2017) is online — please use it for information on the event and for registration.

A strong defence by one black piece is eliminated, but another, yet weaker defence by a second black piece, newly brought into play, substitutes for it. Depending on how the strong defence is eliminated there are three main types of the Dresden theme.
